How to make
Cut the carrots and celery stalk into thin strips. Cut an apple in the same way as well. Transfer the vegetables into a bowl.
Prepare the salad dressing by mixing the mustard, honey and olive oil. Squeeze the lemon juice in the mixture. Peel an orange, break up the orange pieces and add them to the vegetables in the bowl.
Squeeze the juice from the rest of the orange in the dressing.
Season with salt and pour the dressing over the salad. Stir well.
Sprinkle with pumpkin seeds and serve.
